Can we use "Tab" to enter 4 spaces?

I use   quite often to precede a first-line and provide shape to some text, though there is a way you could add an indent wrap if that’s more what you’re after (maybe even with a button in the format bar).

Indent paragraph text?

I believe div style is not whitelisted, you would need a plugin or component. But you can create a wrap bbcode directly in your admin forum. Add these lines in Customize > your theme or component > CSS Common [data-wrap="indent"] { margin-left: 20px; } Then in your post, use this for the text you want: [wrap="indent"] Your paragraph [/wrap]

Tab is used for page navigation for accessibility, so I’m not sure it can be repurposed that easily.
